Interesting Jam Handy film as it's not as Chevycentric as most of these are. This focuses on the many types of printing back then, using steel and chemicals mostly, and how art is transferred to be printed. The chevy connection here is that they're printing Chevy literature, so it's pretty minor. Still, this film was very interesting and educational.
